ATTACHMENT FOR VISES.

To all whom it may concern:

Be it known that LTIENRY G. WEATH- nn LL, a citizen of. the UnitedStates, residing at Elgin, in the county of Kane and State of Illinois,have invented certain new and useful Improvements in- Attachments forVises; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which itappertains to make and us'ethe same.

This invention is an attachment for Vises and the like and relates moreparticularly to vise attachments adapted for'use in connection withclamping roundfwork such as rods, pipes, tubes, etc.

The primary object of the invention resides in the provision of anattachment of the character described, which shall be eX- tremelysimple, inexpensive, practical and, durable and which can be easily andquickly placed in position and readily removed at any desired time. r

Another object of the invention is to provide 'theattachment with aplurality of gripping" members having a vplurality of teeth of peculiarformation which renders it'pos'sible, when the attachment is placedbetween the jaws of the vise, to clamp rods, pipes, etc., of widelyvarying diameters.

lVithv these and other objects in view which shall become apparent fromthe following description taken in connection with theaccompanyingdrawing, this invention comprises a resilient'member havinga plu rality of arms normally spaced apart and being adapted tofrictionally contact with the jaws of a vise, one or both of said armsbeing provided with means for gripping pipes, rods, tubes, etc. for thepurpose of Specification of Letters Patent.

of a spring arm Referring more particularly to the draW- ings, whereinlike characters of reference are employed to designate correspondingparts ofthe several figures, A represents a conventional form of visecomprising a body portion 1, a fixed jaw 2, a movable jaw:

3, said jaws being of the usual fiat facedtype and 'a screw member a.

1 The improved attachment issh'owncom prising 'a spring member-4whichmay be of any preferred construction,illustrated in the drawings asprovided with a plurality of opposed arms .5 normally spaced apart.Preferably rigidly mounted" on each ofsaid arms 5 by means of aconnecting member 6,

isa gripping member 7 having a plurality of teeth 8, adapted. to engagerods, tubes,

etc, and to securely hold them against rotation relative to the visejaws 2 and 3. The connecting member 6, as shown in Figs. 2 and 3, is inthe form of a rivet. In this form of construction the gripping member ispermanently fastened to the spring arms 5,

but in the form ofconstruction disclosed in Figs. 4, 5, 6 and 7, thisconnection is in the form of a dove-tail key 9 fastened securely to Ithe end of the spring arm by means of the rivetlO. The dove-tail key maybe tapered as at 11 to adapt it for engagement with the tapered slot 12forming the gripping member 7 This permits of thegripping memher 7 beingwedged into position on the arm 5 of the spring member 4, and thusrigidly retained against displacement. It will be readily understoodfrom the foregoing construction that the gripping member 7 ,may beremoved at any time for the purpose of replacing it with a new one orwith others of different sizes and shapes for use in connection withdifferent classes of ,work.

As pointed out above the gripping member 7 is provided with a pluralityof teeth 8, which, as will be noted by referring to the drawings, are ofpeculiar formation so as topermit the rods, tubes, etc, of widely varyindiameters being clamped securely 1n any predetermlned position. Asshown, these teeth are preferably wedged shaped and arranged I instep-like formation from the channel 13 upward on either side and insuch manner that the apeXes of the teeth on each block lie on the arc ofa common circle whose center is outside of and in front of the block.The upper face 14 of each tooth is preferably inclined downward and awayfrom the centrally located channel 13, where the other faces 15 of saidteeth 8 incline slig htly to-- Ward the channel 9 in a downwarddirection.

It will be noted from this construction wherein the teeth 8 positionedon the opposite side of the channel 13 incline toward oneanother, thatwhen the members 7 are clamped to the gripping engagement with thematerial being operated upon, the teeth will prevent any rotationthereof in either direction.

To prevent the gripping members 7 from being forced from the vise jaws 2and 55,

ber 7 is provided with only one lug 16 and 17. In this arrangement thelugs are positioned on opposite ends of the grlpping mem- Copies ofthispatent'may be obtainee for bers with respect to each other and thedevice is thus made applicable to vise aWs of various depth of face.

In applying the attachment to a vise, the spring member a is grasped,the arms 5 pressed sufiiciently toward one another to permit of the samebeing readily inserted between the jaws of said vise, the lugs 16 and 17slidably engaging the top and the bottom edges of the vise jaws as shownin Fig. 1. The spring member is then released, thus allowing the arm 5to spring apart into frictional engagement with the jaws and be thussupported in operative position. After the attachment has been placed inoperative p0sition between the vise aws, the material to be operatedupon is held in contact with the gripping member attached to thestationary jaws 2 of the vise A, while the movable jaw 3 of the vise ismoved forward by means of the screw (0, thereby firmly clamping thematerial between the opposed teeth of the gripping members 7 It isevident from the foregoing attachment is not limited to vises of thecharacter shown in the drawings, but may be used in connection withwrenches or clamps or, in fact, any clamping devices having one or moremovable aws.

Having thus described my lnvention, what I claim as new and desire tosecure by Letters Patent, of the United States is A device ofthe classdescribed comprising gripping blocks, a resilient member provided with aplurality of opposed arms, dovetailed keys secured in transverserelation to the arms and corresponding key-ways in the blocks, the taperof the keys and key-ways being such as to frictionally retain the blocksin operative position upon the arms.

In testimony whereof I afiiX my signature.
